Turn off all hot water taps. Press ON/OFF twice.

Check that nothing is blocking the flue inlet or exhaust. Check all vent components for proper connections. Ensure vent length is within limits.

Ensure condensation collar was installed correctly. Verify dip switches are set properly.

Check fan for blockage.

Check that the gas is turned on at the water heater, gas meter, or cylinder. Ensure gas type and pressure is correct.

Ensure gas line, meter, and/or regulator is sized properly. Bleed all air from gas lines.

Verify dip switches are set properly. Ensure water heater is properly grounded.

Disconnect Manifold Electronic Controls to isolate the problem. Ensure igniter is operational.

Check igniter wiring harness for damage.

Check gas solenoid valves for open or short circuits.

Remove burner cover and ensure all burners are properly seated.

Remove burner plate and inspect burner surface for condensation or debris.

Check that the gas is turned on at the water heater and gas meter. Check for obstructions in the flue outlet.

Ensure gas line, meter, and/or regulator is sized properly. Ensure gas type and pressure is correct.

Bleed all air from gas lines.

Ensure condensation collar was installed properly. Ensure vent length is within limits.

Verify dip switches are set properly. Ensure water heater is properly grounded. Disconnect keypad.

Disconnect Manifold Electronic Controls to isolate the problem. Check power supply for loose connections.

Check power supply for proper voltage and voltage drops. Ensure flame rod wire is connected.

Check flame rod for carbon build-up.

Disconnect and reconnect all wiring harnesses on unit and PC board. Check for DC shorts at components.

Check gas solenoid valves for open or short circuits.

Remove burner plate and inspect burner surface for condensation or debris.

Check gas type of unit and ensure it matches gas type being used. Check for restrictions in air flow around unit and vent terminal.

Check for low water flow in a circulating system causing short-cycling. Ensure dip switches are set to the proper position.

Check for foreign materials in combustion chamber and/or exhaust piping. Check heat exchanger for cracks and/or separations.

Check heat exchanger surface for hot spots which indicate blockage due to scale build- up. Refer to instructions in manual for flushing heat exchanger.
